Nearly my final question - promise
I plan to do a few brews, how much yeast should I start off with in each of my 2 litre starters ( the bottle will be 2 litre at least and I think about a litre inside or don't I need as much ) ?
It really depends on the beer. Stronger beers need more yeast, and it doesn't scale linearly. I use the Brewers Friend pitching rate calculator to work it out, and usually overbuild the starter so I can decant some off to make another starter when it comes to the next batch.
